1 Dehumidifier capacity is generally measured by how many pints of water a unit removes from the air in 24 hours. 2  A mini-dehumidifier (1-10 pints) for a bathroom, closet or under a counter usually costs $40-$70.
For instance, Frigidaire offers 30 pint dehumidifiers, 50 pint dehumidifiers and 70 pint dehumidifiers. General Electric offers 30 pint, 40 pint, 50 pint and 65 pint dehumidifiers. You can also purchase a whole-house dehumidifier if you need to control moisture throughout the house instead of simply one room.
